问一道GMAT数学和CR

Inordertowithstandtidalcurrents,juvenilehorseshoecrabsfrequentlyburrowinthesand.Suchburrowingdiscouragesbarnaclesfromclingingtotheirshells.Whenfullygrown,however,thecrabscanreadilywithstandtidalcurrentswithoutburrowing,andthustheyacquiresubstantialpopulationsofbarnacles.Surprisingly,inareaswheretidalcurrentsareveryweak,juvenilehorseshoecrabsarefoundnottohavesignificantbarnaclepopulations,eventhoughtheyseldomburrow.Whichofthefollowing,iftrue,mosthelpstoexplainthesurprisingfinding?

OA是B,我觉得D也没什么问题啊,OA说it指代不清,可是我觉得pronounceditas当中的it明显指代上文所说的work啊,怎么会指代不清呢?
